IMPROVEMENT IN APPARATUS FOR RAISINGILUIDS.

-ebp TO ALI. WHOM IT MAY CONCERN:

Be it known that I, JAMES PARKER, of Camberwell, .county of Surrey,Kingdom of Great ritain and Ireland, have invented certain ApparatusfcnRaising 'and Forcing Fluids and I do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying sheet of drawings, forming a part of thisspecification. i

The said invention relates to the employment of combined steam and airfor raising and forging water and other liquids, the steam and air beingmixed by means of a peculiar arrangement of jets and nozzles, andintroduced into a tank or-reservoir, when itis caused to exert itspressure directly u pon the liquid to be raised without the aid of apump or piston.

Description of the Drawings.

Figure 1 is an elevation showing the arrangement of tanks employed incarrying out my invention.

Figure 2 is a plan partly in section of an arrangement of valves andpipes employed in connection with the said tanks.v

Figure 3 is a side view of the said valves and pipes, and the apparatusfor combining or mixing the steam and nir.

Figure 4 is a'section in the line xx, fig. 3,' drawn to an enlargedscale. Like letters indicate the same'parts in each of the figures. A isthe steam pipe communicating with the boiler, which may be ofanyordinary construction. The said pipe is perforated with a row ofsmall holes, a. A tube o r pipe, B, is arranged parallel with the tubeA, and is l furnished with a series of nozzles, b, each of which isarranged exactly opposite one of the small holes ain the tube A. Whensteam is admitted from the boiler to the tube or pipe A, it .will issuein small jets from the holes -or perforations e, and-passing through theopen space between the said holes and the nozzles b, will enter thelcup-shaped apertures b in the latter, and carry with it a certainquantity of air which is compressed and forced 'through the said nozzlesinto the receiving-tube B. I prefer to make the apertures a in the tubeA about` onetwelfth of an inch in diameter. -Thc air becomes compressedby the steam-jet in passing through the nozzles b, owing to the'expansion of the steamitherein, and to obtainthe proper quantity of airwith the least possible friction, I prefer to construct cach of the said4nozzles with a length equal to about twelve times its internaldiameter. The steam and compressed air are injected into a tank orreservoir', C, containing the water or other duid to be raised orforced, and acts onvthe same directly, without the aid of a piston, anddischarges it from the' tank through suitable outlet apertures. The saidtank C isso arranged, in relation to the surrounding water or otherliquid to be raised er forced, as to refill by gravitation through aflap, D, or other valves opening inwards, in connection with pipescommunicating with the said water or other liquid. If the height towhichvthe liquid in-the tank is to be raised is not more than the heightof a column of water which would balance the steam and air-pressure inthe tank, it is simply necessary to connect a discharge pipe, E, to thebot-tom of the tank C, and

extend the same to the l required elevation. If the liquid is to beraised to a greater height, a second tank is placed at the discharge endof the lirst pipe, a steam and air pipe being connected with thissecondtank.- In the same manner a third tank, or as many as are required, maybe placed above the last one until the required height is obtained; 'lhesteam and air may be caused to act upon the surface of the water in eachtank by means of a tube or pipe, F, in connection with the slide-valve Gemployed in connection with the first tank, and in like manner, theexhaust may, while the same is refilling, escape from each tank throughthe exhaust pipe e vof the same slide-valvc G. Td produce a continu-ousflow of water, two sets of tanks are employed, one set being refilledwhile the other is discharging. I prefer, in working the water tanks,not to empty them completely at each discharge, but to leave a littlewater, which becomes warm, and thereby presents a warm surface to thesteam and air, and consequently prevents some of the loss fromcondensation. A further saving is eected by having aoatingnon-conducting substance upon the water in' the tanks. I also prefer tohave the top of the tanks kept from contact with the water or fluid toberaised.

What I claim, and desire to secure by Letters Patent, is The combinationof the steam p ipe A, and its perforations, and the pipe B, and itsnozzles Z7, with the tanks C, their valves D, or their equivalents,andpipe E, for the purpose specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JAMES PARKER.
